‘Materials’ Science Strand – Amazing Triangles

It’s amazing all the scientific knowledge that can be discovered from a box of cocktail sticks and a bag of mini-marshmallows!!!!

Fifth class used their skills of experimenting, designing and making, investigating, observing and and analysing to conclude that the triangle is a strong shape which is used to support structures.

If a brace is put diagonally across a square, we create two triangles and a much stronger shape. The triangle is a very popular building shape because it is not easily distorted.
